The city's largest and most powerful forging faction, the Hephaestos Clan.
Their skills and standards in forging need no further explanation; since Finn plans to seek cooperation with a forging faction, it is only natural to think of them.
However, there is another important reason Finn seeks collaboration with the Hephaestos Clan.
That is, as a faction with numerous advanced forgery masters, the Hephaestos Clan's forgers are not only skilled in forging but have better combat abilities than general advanced adventurers.
It's inevitable; to become an advanced forging master, one must acquire the development ability of "Forging", and to acquire development abilities, upgrading is a necessary condition.
In this situation, many forgers who are proficient in forging techniques are also capable combatants, such as Chun, the city's strongest forger, who is indeed a first-tier adventurer at Lv.5.
